Recycled parts might very well have the same wear pattern that's causing my problem.

After spending many hours over several days I happened to notice a strange, apparently purposeless aspect of the passenger side wiper arm. Very early on I concluded that the clunk/think sound was the result of the driver's side wiper arm striking the passenger side wiper arm. In a heavy rain, typical to the area, high speed operational inertia would carry it beyond the "park" position.
 
Spent much of the time trying to tighten up the slop in bushings and bearings to prevent teh over travel.
 
In the process of trying to position both wiper arms for least interference possibility I noticed that the passenger side arm had a strange indentation, design, just exactly where the driver's side arm was striking it. On a guess to the purpose, intended purpose, of the indentation I took a hacksaw and cut a section out of the passenger side wiper arm that exactly matched the otherwise needless indentation.
 
Viola...!!
 
It worked.
 
My guess is that someone screwed up a CAD file design aspect somewhere along the way.

At least, your problem is fixed without any major monetary expense. That's great.
